Serrated Fin Tube, High Frequency Welding Tube, ASTM A213 T11, For Furnace and Heater
The Serrated Fin Tube made from ASTM A213 T11 alloy steel and fabricated via High Frequency Welding (HFW) is specifically engineered for high-temperature applications such as furnaces and industrial heaters. The serrated fin structure maximizes turbulence and heat transfer efficiency, making it a superior choice for heat recovery and fuel efficiency in power plants, petrochemical refineries, and thermal processing units.

Increased surface turbulence enhances thermal performance significantly over plain fins.
High structural integrity from HFW process ensures tight fin-to-tube bonding.
Excellent resistance to oxidation and creep under continuous high-temperature conditions.
Longer service life, even in aggressive flue gas or fuel-rich atmospheres.
Efficient in reducing fuel consumption due to better heat capture.
Used widely in:
Furnace convection sections
Crude oil and reformer heaters
Thermal oxidizers
Economizer tubes in boilers
Process gas heaters
Air preheaters and waste heat recovery units
